HINGE.

SPECIFICATION forming part of Letters Patent No. 429,391, dated June 3, 1890.

Application filed October 26, 1889- serial No. 328,239. (No model.)

To all whom it may concern.-

Be it known that I, MCGUIRE SLANE, of Bell Ranch, in the county of San Miguel and Territory of New Mexico, have invented a new and useful Improvement in Hinges, of which the following is a full, clear, and exact description.

This invention relates to double-jointed hinges-that is, hinges in which the two leaves or sections of the hinge are provided with two parallel joint-pins arranged at suitable distances apart and connected by one ormore yokes or link-pieces; and the invention consists in a hinge of this description of novel construction, substantially as hereinafter described, and pointed out in the claims, whereby the hinge may readily be used either as an invisible or concealed one from the outside, or as a flush-hinge, and whereby it does not require to be set deep in the wood, thus giving it a neat appearance and making it more practicable for many articles or pieces of furniture.

The hinge is mainly designed to be used on pianos and fine furniture, including cabinetware of different kinds; but it may also be used on boxes and other articles.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a front view of the hinge applied to a lid and adjacent part when fully open; Fig. 2, a side view of the hinge closed with the parts to which it is applied in section, the section being taken on the line w 00 in Fig. 1; Fig. 3, a further side view of the hinge partly open with the parts to which it is applied in section, and Fig. 4 a still further like side view when the hinge is fully open. These several views show the hinge applied so as to conceal it or make it invisible in the working of it and when closed. Figs. 5 and 6 are views in perspective of the two leaf portions of the hinge detached; Fig. 7, a perspective view of a top or inner marginal longitudinal piece or cover which is used or applied to each of said leaf portions; and Fig. 8 is a perspective view of one of the yoke or link pieces of the hinge. Fig. 9 is a side view of the hinge closed with the parts to which 'itis applied in section, and showing it merely as a flush and not as an invisible hinge; and Fig. 10 is a similar view to Fig. 2, but showing the hinge as concealed or made invisible from the outside by an increased thickness of wood as a covering, and also representing by dotted lines the lid part in its fully-open position, as in Fig.4.

,A indicates what may be termed the fixed part, to which the hinge is applied, and B the lid part thereof. In .Figs. 1, 2, 3, 4, and 10 the recesses a a, which are made in these parts to receive the hinge, are notrepresented as through ones in direction of the thickness of either of said parts, but as stopping short of the outside surfaces of them, so as to leave a covering-piece b of the wood over the longitudinal marginal portion of the hinge on which the joint-pins c c are arranged, thereby making the hinge invisible from the outside. By increasing the distance apart of these joint-pins or two centers of the hinge then these covering portions b b of the wood will be of an increased thickness, as shown in Fig. 10 when compared with Figs 2 and 4. Said marginal portions of the hinge-that is, of the arms d cl of the leaves C D of the hinge-also, the meeting marginal portions of the parts A B, are respectively formed with concave and convex surfaces 6 f, arranged to roll or fit one within the other to give a good support to the hinged parts at the joint and to make the hinge-joint a close one throughout the length of the hinged parts.

WVhen it is not required to have the hinge an invisible or concealed one from the outside, then the recesses a a in the parts A B, made for the reception of the hinge, are through ones in direction of the thickness of said parts A B, the hinge-sections being of a suitable width to accord, as shown in Fig. 9. In this case the hinge will be merely a flush onethat is, will have its longitudinal marginal portion in the same planes as the inner and outer face surfaces of the parts A and B. To thus make the hinge a combined or convertible invisible and flush one, each leaf-section C or D of the hinge is made or provided with what may be termed a I00 solid top--that is, with an inner longitudi nal marginal piece or cover E, having lugs g on its inner surface, which lugs are arranged to be intermediate of the arms d d of the leaves, and to receive between them and said arms the links or yokes G that unite the two joint-pins c c of the hinge, said links or yokes that are fitted to turn loosely on the pins 0 0 being made with double-end lugs h h, which receive in between them the lugs g of the joint-covering piece E, and the pins 0 c, which have fixed axial centers and do not Work in slots, passing through holes made in each of the lugs g and h and arms (6 of the hinge. Thus the joint portion of the hinge is fully covered on the outside by the longitudinal covering strips or pieces E,,so that when the hinge is a flush one no joints in transverse arrangement to the pins 0 0 will be seen. At the same time the hinge can readily be used as an invisible or concealed one free from all exposure of its joints, as hereinbefore described.

The links oryokes G are of double angular or equivalent form 011 their sides opposite to the lugs h h, as shown at 7c, and thelongitudinal walls of the recesses in the leaves C D between the arms d are correspondingly beveled, as at Z Z, to receive the angular surfaces of the links or yokes Within them when the hinge is fully closed, and the hinge, constructed as described, has a flat leat hearing within the recesses a a in which it fits, and said recesses do not require to be made of any extra or increased depth to accommodate the hinge or to provide for the working of it.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a double-jointed hinge of the charac ter herein described, the covering strips or pieces E, with their attached lugs g applied to each leaf or section of the hinge, substantially as and for the purposes herein set forth.

2. In a double-jointed hinge, the combination, with the leaves 0 D of the hinge having attached arms (1, of the covering strips or pieces E, with their attached lugs g,thelinks or yokes G, having double-end lugs h, and the parallel joint-pins c 0, having fixed axial centers, the Whole being constructed andaranged for operation together, essentially as and for the purposes specified.

MCGUIRE SLANE.
